Aviation В· Geophysics В· Geospatial Solutions В· Since 1996
GEOSAN is Mongolia's premier provider of airborne and ground geophysics, aerial geospatial solutions and charter flight operations, turning the country's hardest terrain into decision-grade data.
Aviation, geophysics and geospatial solutions under one operator. We own and fly our own aircraft, run our own instruments, build digital twins with Bentley's platform, and process our own data, so a survey flight, a charter and a 3D site model all start from the same team.
Geophysics surveys, digital twin modelling, aerial mapping and charter operations, all in one place.
Airborne and ground surveys covering magnetic, radiometric, gravity and electrical methods. Over 70 projects and 500,000 line km completed across Mongolia and Asia.
Aerial survey, photogrammetry and digital twin solutions built on Bentley's iTwin platform. From orthophotos and terrain models to live asset models that update with each drone pass.
Cessna Grand Caravan charters for cargo, medevac, tourism and remote-site logistics, with field aerodrome operations and full in-house aircraft maintenance across Mongolia.
Home base, our hangar at sunrise
Our first contracts in 1998 were near Oyu Tolgoi and Gatsuurt for BHP Billiton. Three decades on, clients still choose us for the same reason: we get the aircraft to the block and the data holds up.
Nearly the entire range of ground and airborne surveys available today: magnetic, radiometric, gravity, IP/resistivity, EM and borehole logging, all in-house.
Industry-standard acquisition systems and a team recognised for technical expertise in geophysics, geodesy, geology and aviation.
Two Cessna Grand Caravans and the ability to open field aerodromes mean we reach sites across the Gobi, mountains and steppe — and abroad.
Whatever the discipline, every engagement follows the same straightforward path from first contact to finished deliverable.
A survey block, a mapping area or a charter route. Send us the details and the timeline.
We scope the method, aircraft and instrumentation, then quote a fixed price and schedule.
Our own aircraft, crews and instruments handle the mission, quality-checked in the field.
Processed, interpreted deliverables in the format your team works in, ready to act on.
From global mining majors to Mongolia's national agencies, we've delivered surveys, flights and geospatial data since 1996.
300+ projects completed across Mongolia, India & the broader Asia-Pacific region
Send us the block, the corridor or the deployment. We'll come back with a flight plan and a proposal.
